I have ME/CFS and the fact that we're expensive to the general public seems to be the only reason there is any public money spent on treatments and cures at all. However, Canada and others are finding that medically assisted suicide offers an even cheaper alternative solution. So instead of money spent on treatments and cures we get subtle and not so subtle encouragements to kill ourselves, and I expect the problem to keep getting worse. I.e. I don't think the actual emergent behaviour for shared healthcare costs is as altruistic as you appear to except.
